To all whom t may' concern:

Be it known that I, HOWARD I. MORRIS,

acitizen of themUnited States, residing at Cleveland, county ofCuyahoga, and State of Ohio, haveinvented certain new and usefulImprovements in and Relating to Ap paratus for Supplying, Heating, andDispensing Liquids, Aoi 'wh ich the following is a specification.

This inventionrelates to an apparatus for supplying a liquid at anydesired degree of temperature and maintalng such supply at approximatelythe desired temperature,

whereby it can'be used at will; more parbeverage; and as showing oneapplication of such an apparatus, I havedisclosed it as applied to themaking of coffee, pr'eferably-orV the type in which the heated water andconcentrated liquid coffee are simultaneously dispensed into areceptacle and served for drinking purposes.

My invention comprehends an apparatus in which a liquid is automaticallysupplied and maintainedat the desired temperature l and in whichthedispensing of the liqudor of a plurality of liquids are controlled bythe temperature 'of that liquid which is l .maintained at thepredeterminedl temperature; and-accordingly one object ofthe in ventionis vto provide a dispensingmean's which is controlled by the temperatureof the li uid or one of the liquids'to .be dispense Whereby.`theoperation of they dispensing means `is yreventeduntil such liquid has.attainedthe esired degree of tempera-4 ture suitable fOr-making thebeverage.

` Anotherobject of the invention is to provide an improved apparatus forsupplying and maintaining heated liquid in a charged as desired.

Another Object of .thinvenaoa is to pra.

vide an im vroved ap aratus for lrrr'laintainingl a lpre etermin.quantity of heated .liquid-in a receptacle so arranged that4 the sourceofiheated liquid. supply umay utilolding'` I receptacle from which thellquid may beI dis? a. Water supply pipe 2, wherebythe water will besupplied as fast -as it is used. 3 inized to either maintain the liquidat the desired temperature or supply liquid to the receptacle as theliquid is discharged therefrom.

Another object of the invention is to provide an improved dispensingmeans for two or more liquids, whereby the same may be uniformly mixedat all times. Aurther object of the invention is to' provide an improvedbeverage generating and dispensing apparatuscapable o f operation in aneconomical manner with respect to both labor and fuel cost.-

` Other objects of the invention will be apparent to those skilled inthe art to which the invention relates from the following descriptiontaken inconnection with the accompanying drawings, wherein is shown forillustrative purposes one embodiment of my invention. I

Fig. 12 is. a detail sectional view illustrating a slightly modifiedform of construction of thev dispensing valve.

Referrin to the drawings, 1 indicates a supply ta for a' liquid that isto "be dispensed, as will be later set forth. Where the linvention isembodied in an apparatus for makingcoffee, I fill the tank` 1 withwater., By preference, the tank 1 is connected with dicates as anentirety means for heating the water inthe tankv 1. The heating meansmay comprise agas burner i of suitable construction, connected to a gassupply pipe 5.

The flow of gas through the pipe 5 may be cut ofl' by a valve 6. -9indicates a suitable thermostatic device`extending through an opening intheside wall of the tank 1 and .into the` water therein, as shown inFig. 1.

The elements of the thermostatic device act on one or more levers,mounted in the casing 10, which is interposed in the gas pipe 9, and thelevers in turn control the opening and closing of alvalve inthe casingto permit or cut 0H the flow of gas therethrough to the burner 4, tothereby maintain the water at from which the water is dispensed asneeded through a dispensing mechanism indicated as an entirety at 14.The receptacle 13 pref- *erably comprises a cylindrical wall 15, a bot1tom v16 and a closure 17..

18 indicates a combined heating and supply means for the holder 13,whereby heated water is supplied to the holder and the water in theholder is maintained in heated condi- .tion and at substantially apredetermined temperature. Of the combined liquid heating andsupplymeans, 19 indicates a pipe leading from the upper portion of thetank 1 to theJ upper portion of the holder 13. By

preference the' holder 13 is disposed directly above the tank 1, inwhich event-the pipe 19 extends vertically through a suitable open- Yber 21 an ing 19a in -the bottom 16 and then upwardly within' theholder, as shown in Figs. 1 and 2. 20 indicates a coil ofsuitableconstrution disposed within the holder v13 and connectedto theupper end of the pipe 19, preferably through a casing 21-of a valvemechanism, indicated as an entirety at 22, to be later described. Theopposite or discharge end'of the coil 20- is connected to a pipe 23,which preferably leads to the lower portion of the tank 1. From theforegoing description it will be apparent that the pipe 19, coil 20 andpipe 23, by reason of the connection of the pipes 19 and 23 withthe'tank 1, form a hot water circulating system to permit the waterheated in the tank 1 to rise in the pipe V19 and flow through the coil20 and back to the tank through the pipe 23, and that such heated waterwill operate to heat and maintain heated the water in the holder 13. Thevalve casin 21 comprises'a cylindrical mema conduit-21b surrounding thecylindrical member 21a and provided with a discharge nipple 21, which isconnected in any desired manner to the upper vend of the coil 20. `Thelower end of the cylindrical member 21a is open and provided with screwthreads, to which the upper end of the pipe 19 is screw threaded. 24indicates a slot formed in the side Walls of the cylindrical member 21ato form a passage from the cylindrical member 21 into the-conduit 2lb,whereby the heated Water flowing upwardly in the pipe 19 may beconducted to the coil 20. The upper end of the cylindrical member 21Elis provided with an end wall 25, in which is formed a discharge port 26,having a valve seat 27 at its inner or lower end. 28, 29, indicate apair of connected valves, the former serving to engage the seat 27 toclose the port 26 and the latter serving to close the opening or slot24, the connection between the valves being such that one is closed whenthe other is open and vice versa. The valves 28, 29, preferably comprisea cup or piston shape memberl 31, the annular walls thereof slidablyfitting the inner walls of.

the cylindrical member 21l and movable downwardly to bridge the slot 24and close it (see dotted lines in Fig. 8) and the head thereof beingprovided with an annular boss which serves as a valve to engage anddisengage the seat 27 lVhen the valves are in the position shown in Fig.8, the port 26 is closed and the slot is open, and accordingly theheated water will circulate through the pipe 19, coil 20, and pipe23back to the tank 1; but if the valves are o eratedto theirotherposition, the slot 24 wi l be closed land the port 26 opened, in whichevent the circulation of the heated water will be cut off from the coiland caused to flow through the port 26 into the holder 13, openings 32being formed in the head of the valve meml ber 31 to permit the flow ofthe water therethrough. This latter operation may be effected to eitherfill the holder 13 or to replace any heated water that has beendischarged thererom. It will thus be seen that the tank 1 and pipe 19serve as a single source to (l) supply or fill the holder 13 with heatedwater and (2) maintain the waterin the tank 1 heated at thev desiredtemperature. By closing the slot 24, circulation of the water in thereverse directionl through the coil 20 is prevented whenever the port 26is open. Accordingly it will be understood that I prevent cold water, orwater that is cooler than that being supplied by the pipe 19, fromentering the holder 13 during filling of the latter. In this connectionit may be noted that the thermostatic devices 9 are properly adjusted inorder that the burner 4 will heat and keep heated the water in the tank1 at a high enough temperature to insure the desired degree oftemperature in the, circulation pipe and the holder 13.

32 indicates a rod or stem connected to the valve member 31 foroperating the'valves 28, 19.

l 33 indicates a wall spaced fromv but pref-` erably integrallyconnectedby webs 34 with the end wall of the valve casing 21. The spacesbetween the webs 34 form openings for the discharge of the water flowingthrough the port 26. The Wall 33 is formed Wlth an opening 35-Whichslidably receives the valve stem, the walls of the opening co-loperating with the inner walls of the cylin? drical member 21a tosupport the valve mem-l ber 31. The rod 32 may be operated in eitherdirection manually, but I prefer to operate it automatically, forexample by a fioat 35 so that it may be actuated by the (1) lowering ofthe water level in theholder k13, dueto dispensing operations, to openthe port 26 and (2) rise ofthe 'level of the water, due to filling ofthe holderto close the port 26. The float 35 isconnected to one end of alever 36. The other end of thelever is pivoted in any desired manner ona7 bracket 37, preferably comprising a pair of f arms integrallyconnected to the valve cas# ing 21. As shown i'n Fig. 7, the lever extends diametrically across the casing 21 4in position to be pivotallyconnected, in a well known manner, to the upper end of thevalve stem 32.

The cover 17 preferably comprises an annular member. The outercircumferential edge ofthe cover is provided withl a flange and adepending collar which engage the upper circumferential edge of the sidewall 15.

The-inner circumferential edge of the cover.

17 is provided with a downwardly and inwardly inclined wall 17', whichis Aadapted to receive and support a container 38 in in` vertedposition. The container 38 serves as a separate source of supply for aliquid which is to be dispensed simultaneously With the liquid suppliedto the holder 13, In the present disclosure of the preferred embodimentof the invention the container -holds and supplies concentratedcoifee inliquid form. It will be understood that the container may be located inany convenient place; it being shqwn'associated'with the holder 13 forillustrative purposes only.

The container 38 is preferably protected by a housing39, which may beformedin its side wall with a slot 40"to show 'theamount of coffee thatis contained in the vcontainer 38' at all times. When the. container 38Iis disposed as shown,I its mouth projects into a basin 41 to form aseal. The basin 41 is provided with two or morearms 42, each of whichrests on a bracket 43 secured tothe inner surface of the side wall 15.The basin 41 may be provided with a screen 44. The bottom of the basin41 is formed with an opening to receive a nipple 45, which in turnisponnected, by means of a union 46, to a i7 leading to the dispensingmechamsm 14. y

Of the` dispensing mechanism l14, 1.4al indicates a faucet body ada tedto be connected at 14a to but exten ing through the side wall 15 of theholder- 13 near or adjacent its bottom. 'Ihe outer end of the faucetbody is .turned or bent downwardly for well known reasons. Theconnection '14" for the faucet body 14a is of a liquid tight character.14h, 14, indicate ducts or conduits extending through said faucet body,preferably from its inner or inlet end to its outer or discharge end.`The conduit *14b opens into the receptacle 13 to receive the Watertherefrom, but the conduit 14c is provided at its inner end with anipple 14d, to which the pipe 47 is connected in any desired manner, forexample, by a union 48. At 14", the faucet body is formed with a conicalrecess, into which the conduits 14", 14, are merged, such recess servingasia 'seat for a conical valve '14H The valve 14t` is formed with ports14g, 14, so disposed that (1) when the valve is in one position (seeFig. 2), their opposite ends register with the adjacent open ends oftheconduits 14", 14, respectively, thereby permitting iow of the liquidsthrough the two conduits simultaneously and (2) when' the valve 14f isin Aits other position (see F igs. 3 and 4), bothconduits will beclosed. The valve 14t extends upwardly and is provided with ahan dle 49,by which thevalve is oscillated in its seat. 4The lower end of the valve14-f extends through the lower side wall of the lfaucet body 143,-asshown at 50,- such. ex-

tended .end being screw threaded to receive a pair of nuts 51, 51-seeFig. 3. By preference I interpose between the vfaucet body 14'nl and theadjacent nut a spring 52 whichn `liquids from the holder 13andVcontainer-38 are simultaneously discharged or dispensedl at the outerend 'of' the faucet` body 14a into lsome receptacle, such as a cup (notshown),

wherein vmixing of the liquids (water and concentrated coffee).taesplacbut it will be understood that the conduits 14", 14",-lcouldmerge one with another at or near the outer end of the faucet body14a topermit mixing of the liquids while iowingv to the receivingreceptacle, as shown in Fig. 12. 125

- The operation ofthe valve 14t is preferably cont-rolled by thetemperature of the liquid within the holder` 13. For this purpose -Iprovide means, indicated as an entirety at 53, forlocking and unlockingthe handle 49 or' an arm 54 rigidlyr connected thereto and thermostaticdevices, indicated as an entirety at 55, which control the locking andunlocking means 53.

Of the thermostatic devices 55, 56 indicates a casing provided on theinner side of the wall 15, preferably in close proximity to thedispensing mechanism 14. The casing 56 is preferably formed integralwith a plate 57 which covers an opening 15a formed in the wall 15, suchplate being'provided to form a rigid support for the thermostaticdevices 55, the dispensing mechanism 14, and the locking and unlockingmeans 53. The plate 57v may be riveted in position in a well known way.The casing 56 is formed in 'its upper wall with an opening 58, in whichissupported a copper tube 59. The copper tube 59 constitutes one elementof the thermostatic devices .55, the other element 59a being arrangedwithin and connected at its upper end to the upper end of the tube 59.The. tube 59 being formed of cop-per readily responds to changes intemperature of the water in the holder 13. As the temperature ofthewater rises, the tube expands and moves the element 59a endwise; coolingof the ywater causes the tube t0 contract, and lsuch contraction movesthe element 59a downwardly. The lower end of the'el'ement 59a engages anarm 60 fixed, to-

the holder reaches a higher or lower degree of temperature, -as desired.

The thermostatic devices may be arranged in any desired position in theholder 13, but by arranging them vertically and adjacent the wall 15,ample space is provided for the coil 20 and pipes 19 and 23. A furtheradvantage obviously results in arranging the thermostatic devices inclose proximity to the dispensing mechanism V14 in that the controlofthe latter will be de-` pendent upon the temperature of the'waterwhich surroundslthe inlet to the water con- `duit 14b of the dispensingmechanism 14.

64 indicates a casing. connected. to the outer face of the plate 57 andco-operating with a base plate 65, preferably formed integral with theplate 57, to form an enclo.

`sure for the locking and unlocking means 53.

The `base plate 65 and outer side-.wall ofv the casing 64 are cutawayoto form a slot throughl which the arm 54 moves when the valve 14tis operated.. 66 indicates a lug preferably for'med integrally with theplate 57 and base plate 65. The lug is formed with a bearing opening fora pin 67 on which a dog 68 is mounted for oscillation. The dog isnormally arranged in the path of movement of a shoulder 54a provided onthe arm 54 so as to .lock the arm against movement to the Valve openingposition, The dog 68 preferably terminates in a knife edge and theshoulder 54tt is inclined inwardly to form a knife edge at its upper orfree edge. As -a result of this form of construction, movement of thearm will be prevented as the inclined face ofthe shoulder will guide thedog downwardly against the Arear portion of the shoulder, unless the.dog

68 has been moved to a position to entirely clear the shoulder 54a. Thedog 68 is preferably held in its normal position by a spring 69connected to the tail of. the dog and the casing. 64 (see Fig. 5). 4Aswill be understood fromFigs. 3`and 4, the lever 63 is arranged in thevertical plane of the dog 68 and bears at its free end on the tail ofthe latter, so that when the thermostatic elements act tov relievepressure on the arm 60, the lever 63, under the influence of a spring70, will operate the dog 68 to move it to a position out of the path ofmovement of the arm 54, thereby unlocking the latter. The thermostaticdevices 55 are adjusted so that the thermostatic element 59a will engagethe arm 60fand through it elevate the outer end of the lever 63 so longas the temperature of the water is below that degrec atwhich it isdesired to dispense 1t.

But as the water rises in temperature, the

permit of uniform -quantitiespf the liquids to flow through them formixing when the 14h, being of a predetermined, size, they valves for theconduits are opened. Where a beverage, such as coffee, is to be made, itmay be` desirable to change the strength thereof to suit differenttastes or to make a uniform beverage where the ingredients themselves,before mixing, are not uniform. To permit of the varying of theproportions of the liquids to be mixed, I combine with `the valve 14t asupplemental valve 71 whereby the size of one vport therethrough may bereduced to restrict the quantityA of liquid which flows through' itduring' the period that the valve 14 remains in the open osi-y tion,U ascompared to that which ows through the other port in the same period.The supplemental valve 71 is preferably arranged to restrict the portthrough which the concentrated coffee Hows. For this purpose, the bodyportion of the valve 14t is formed with a conical opening 72, extendingfrom its inner end downwardly, to form a seat for the valve 71. As shownthe valve 71 is formed with a port 73 which registers .'at its oppositeends with the port 14h formed in the valve 14. The valve 71 isadjustable about its aXis to move its port out of registry withrthe port14h to a greater or less extent, as desired. Such adjustment has the .ieffect of restricting the size of the port 14h A so that the quantity ofconcentrated coii'ee discharged or dispensed will be reduced.

The valve 71 is provided at itsgupper end with a stem 74 to which issecured a handle 75.. The handle 75 is preferabl provided with a pointer76 which, is mova le relative to a graduated scale 77. TheV scale 77 isprovided on an arcuate late which forms a part of the arm 54. 78indicates a cap having screw threaded connection with the internal wallsof the hub 49 connecting the handle 49 and `arm 54 together. The cap 78forms an abutment for oneA end of acoiled sprin 79 surroundingthereduced portion of t e valve stem -74 and bearing at its other endagainst the body portion of the valve 71 to maintain the latter in itsseat. 'v

80 indicates an overflow pipe 4for the l holder 13 leading to anysuitable place of discharge (not shown). The pipe 80 pref` erablyextends through the bottom oftheV holder13. 81 indicates a valved drainpipe leading from the bottom 16 of the holder 13; The pipe 81 lmay beconnected td the overflow pipe 80 for lead to a suitable place ofdischarge (not shown).

Th'ose portions of the :pipes 19 andl 23,4

which are arranged inside the holder 13, are

I `preferably connected by unions 19f, 23', re-

spectively, within the holder withpipesections mounted in o eningsformed in the bottom ,16,of the ho der 13. This arrangement permitsthese portions of the pipes w19, 23 and the coil 20 to be positionedinvand `removed fromthe holder 13, as a unit.

From the foregoing description it will'be se'enlthat I provide for'therapid and economical dispensing of a plurality df liquids. It willalso be seen that I provide for the continuous supplyy andheatingof one0fthe liquids in a simple manner. The construction is such that one'ofthe `liquids may `be automatically supplied and automatically maintainedat the desired, temperature,

thereby saving in ,fuel vcost. "My apparatus is also advantageous forthe reason that all labor involved in filling and' refilling the supplytank' orthe holder and attending to the heating means is eliminated.BlyA `controlling the dispensing mechanism 'b v'the temperature oftheliquid in one of the holders, premature idispensing of the liquid orliquids 'is prevented.'` 'As the lvalve for one liquid discharge conduitis. common to shown in Fig. 4 to the position shown in Fig. 2 to open.the discharge conduits 14",

14. 'To limit the movement of the handle in either direction, I prefer'to provide the4 faucet body with projections 82, 83, which are adaptedto be engaged by a-pin 82 depending from the handle. l

85 indicates a faucet, preferably connected in the circulation pipe 23,to permit draining vof the tank 1 when desired.
